Je précise que j'ai supprimé mon .minecraft plusieurs fois car il y avait énormement de mods installés ainsi que de map saves etc... le seul mod que j'utilise à temps plein est Optifine 1.8.4 ainsi qu'un pack de textures Faithfull 64x64. Tout mes graphismes sont baisés au minimum car mon PC est très peu performant :/ je précise aussi que j'ai 1 ou 2 launcher modé installé telle que ArcaniteV4 qui n'est pas dans le dossier .minecraft c'est un autre dossier mais sa fait environ une semaine qu'il est installé et sa ne crashai pas avant donc si quelqu'un à la solution qu'il m'aide svp :(
